Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product data management systems fail to distinguish between disposable and reusable trays, leading to inefficiencies in waste management and environmental impact.
Innovation Solution
A product data management device that identifies and manages reusable trays by using RFID tags or coded symbols, determines tray type through imaging, and calculates and refunds security deposits, integrating with POS systems for seamless transaction processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If tray information acquisition and determination functions are added to distinguish reusable trays, then environmental sustainability and waste management improve, but device complexity increases
Solution Approach 1:
The patent introduces a determination unit as an intermediary component that receives tray information from the tray information acquisition unit and determines whether the tray is reusable or disposable. This intermediary layer manages the complexity by centralizing the decision-making logic, allowing the system to distinguish tray types without requiring complex modifications throughout the entire system architecture.
Solution Approach 2:
The system implements feedback mechanisms where the determination unit outputs messages indicating whether the tray is reusable, and this information is fed back to the output unit for display or further processing. This feedback loop enables the system to adapt its behavior based on tray type, improving waste management while maintaining manageable complexity through structured information flow.
2Productivity
If tray identification and determination functions are integrated, then operational efficiency improves, but device complexity increases
Solution Approach 1:
The patent merges the tray information acquisition function and the tray determination function into a single integrated system. The tray information acquisition unit and determination unit work together as a unified subsystem, allowing the system to identify and classify trays in a single operational flow, thereby improving productivity without requiring separate independent systems for each function.
Solution Approach 2:
The determination unit serves multiple functions: it receives tray information, determines tray type (reusable or disposable), and outputs determination results. This multi-functional component improves operational efficiency by consolidating multiple tasks into a single unit, reducing the need for separate specialized components and simplifying the overall system architecture.
3Loss of information
If message output for reusable tray identification is implemented, then information accuracy improves, but device complexity increases
Solution Approach 1:
The patent extracts the message output function as a separate output unit that specifically handles the communication of tray determination results. This extraction of the information communication function allows the system to maintain high information accuracy by dedicating a specific component to this task, while the output unit itself remains a relatively simple interface that does not add significant complexity to the core determination logic.

AI summary
A product data management device comprising a reception unit that receives the designation of a product to be weighed, a tray information acquisition unit that acquires tray information of a tray used for the product, and a determination unit that, when designation of the product has been received by the reception unit, determines, on the basis of the tray information acquired by the tray information acquisition unit, whether the tray used for the product is a first tray that is discarded or a second tray that is reused, said product data management device further comprising an output unit that, when it is determined by the determination unit that the tray used for the product is the second tray, outputs a message indicating this fact.
